Over the past couple of decades, almost all American art museums have claimed a mission to reach out to “underserved communities,” yet none of them have acknowledged that these communities have their own well-developed aesthetics of art and material culture. They differ from the mainstream, and the institutions have not been willing to embrace aesthetic values beyond their own. The first part of “The Freedom Principle” is remarkable for doing just that: exhibiting art–and music–that was selected by a group of artists largely excluded from the mainstream of their period, who developed a different set of aesthetic aspirations and standards.
